First Claim
Patent Images
1. A polyaxial pivot housing for an external fixation system, comprising:
- a collet body including a threaded portion and a threaded bore hole configured to attach to an external fixation clamping assembly;
a spring mechanism housed within the threaded bore hole,a spherical member configured to be partially received by a cavity that is formed in the collet body, the spherical member including a threaded post that is configured to attach to a support member of an external fixation frame; and
a threaded locking collar that is configured to orientationally lock the threaded post with respect to the external fixation frame by compressing the spherical member into the cavity as the threaded locking collar is mated with the threaded portion of the collet body.
